Regurgitation is the return of stomach contents up the esophagus and into the mouth. It may occur along with gastroesophageal reflux disease (GERD).
Around 80% of people with GERD may have regurgitation as a symptom, which can vary in severity.
This article looks at GERD and other causes of regurgitation, prevention, treatment, and when to contact a doctor.
Regurgitation is when stomach contents flow back up the esophagus and into the mouth.
The esophagus is the tube joining the throat to the stomach. The lower esophageal sphincter is a muscle that prevents stomach contents from leaving the stomach and traveling back up the esophagus.

With regurgitation, the food that comes up may leave the mouth, particularly in infants. Regurgitated stomach contents may appear the same as vomit, although the action of vomiting is generally more vigorous.
Reflux is when stomach contents, such as stomach acid or food, travel back up the esophagus from the stomach. People may taste reflux in the back of the throat.
The difference between regurgitation and reflux is that regurgitation is when reflux enters the mouth.
There are various reasons a person may experience regurgitation.
Gastroesophageal reflux (GER)
GER is the term for stomach contents traveling back up the esophagus. GERD is a chronic condition in which people have ongoing symptoms, and it may lead to complications.
Regurgitation is a
Regurgitation is common and typical in infants due to factors such as:
- having a smaller esophagus, which is less able to hold larger volumes
- consuming large quantities of liquid meals
- spending prolonged time lying down
Doctors may refer to regurgitation in infants as functional infant regurgitation if there is no underlying health issue causing the condition.
Functional infant regurgitation is present if it occurs in the first year of life and an infant has regurgitation for at least 3 weeks, occurring at least twice a day.
Rumination syndrome is an eating disorder in which people involuntarily regurgitate food they have recently eaten.
The regurgitation of food usually happens within
Avoiding lying down for at least
- citrus fruit, tomatoes, and other acidic foods
- foods high in fat
- spicy foods
If an infant is regurgitating, comforting and soothing them may help. Some people find that it helps to move the child to a calm, quiet environment with dim lighting and relaxing sounds.

GERD can be serious without treatment. Over time, it
- esophagitis, an inflammation of the esophagus that may lead to ulcers
- esophageal stricture, a narrowing of the esophagus that can cause swallowing problems
- Barrett’s esophagus, a change in the tissue lining of the esophagus, which can increase the risk of esophageal cancer
It is best to contact a doctor if a person thinks they may have GERD or they experience any complications affecting the mouth or throat.
Although rumination syndrome is
In infants, symptoms present other than regurgitation may indicate a health issue. This includes:
- refusal to eat
- breathing problems
Managing GERD may help reduce symptoms such as regurgitation. Treatment for GERD
- losing weight
- quitting or avoiding smoking
- elevating the head 6–8 inches off the bed while sleeping
- altering diet to avoid potential symptom triggers
- taking medications, such as proton pump inhibitors or H2 blockers, which reduce the amount of acid the stomach creates
- undergoing weight loss surgery
If other treatments are not effective, a person may undergo fundoplication. This is a surgical procedure to join the stomach to the end of the esophagus.
Preventing factors that
- losing excess weight and maintaining a moderate weight
- avoiding smoking and secondhand smoke
Certain medications may also cause or worsen GERD, including:
- nonsteroidal anti-inflammatory drugs (NSAIDs)
- tricyclic antidepressants
- calcium channel blockers
- some asthma medications

The outlook for those with regurgitation may depend on the underlying cause.
According to a 2020 article, proton pump inhibitors may help in around 15% of cases of regurgitation in people with GERD.
Procedures to help prevent reflux may be more successful. This includes fundoplication and magnetic sphincter augmentation, where doctors implant a magnetic device to help the lower esophageal sphincter close. However, healthcare professionals may be more likely to use fundoplication in most cases.
Research has shown that these procedures have a success rate of over 85% in people with GERD and regurgitation.
Regurgitation is a common symptom of GERD. It is also a common and temporary condition in infants.
Rumination syndrome is another cause of regurgitation and is generally reversible.
Diet and lifestyle changes, medications, and surgery may help manage regurgitation with GERD. Anyone experiencing symptoms of regurgitation or GERD should speak with a healthcare professional.
